The existing implementation had little to do with VC1.
This could be implemented by adjusting the reference frames
ithemselfs but that would make frame multi-threading difficult.

Both don't change anything in the context between frames.

Fix checkheaders when vid.stab is not available.

The frame must be writable if the show option is set, otherwise pass the
frame unchanged.

vidstabdetect and vidstabtransform common functions for interfacing
vid.stab are in libavfilter/vidstabutils.c

Make clear that the options accept an expression.

Honour declaration order in filter implementation, for shorthand
consistency.

Also favor the video filter name for indexing, in case there is an a*
audio filter variant.

In particular, fix h/H commands in case h and H are not specified as
initial parameters.
